Project Labor Agreements. Building and construction trades workers are one of the hardest hit groups in the nationâs job crisis. Yet state lawmakers, backed by construction industry CEOs, want to cut the wages of those workers by eliminating prevailing wage laws and project labor agreements (PLAs) on public construction projects.
There are many algorithms to solve scrambled Rubik's Cubes. The maximum number of face turns needed to solve any instance of the Rubik's Cube is 20, and the maximum number of quarter turns is 26. These numbers are also the diameters of the corresponding Cayley graphs of the Rubik's Cube group. An algorithm that solves a cube in the minimum number of moves is known as God's algorithm. There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. The second is to count the number of face turns.
The current world record for a single solve of the 3Ã3Ã3 in competition is 5.25 seconds, set by Collin Burns in April 2015. Speedcubing is a popular activity among the international Rubik's Cube community, or cubers. Members come together to hold competitions, work to develop new solving methods, and seek to perfect their technique. As a part of the community, puzzle builders and modders try to invent new forms of combination puzzles.
